WTAP/IGF2BP3 Mediated m6A Modification of SOD2 mRNA Aggravates the Tumourigenesis of Colorectal Cancer.

Wilms tumor 1-associated protein (WTAP) has been validated to be a crucial regulator in the tumorigenesis and advancement of diverse malignancies. This study intended to probe the impacts of WTAP on colorectal cancer (CRC) progression from the perspective of N6-methyladenosine (m6A) modification. The differential expression patterns of WTAP in clinical CRC samples and cultured cell lines were validated via qRT-PCR and western blot.

FTO rs1121980 polymorphism contributes to coronary artery disease susceptibility in a Chinese Han population.

Background: The fat mass and obesity-associated protein (FTO) has been showed to be involved in the pathogenesis and progression of coronary artery disease (CAD). However, the effects of FTO variants on CAD risk remain poorly understood. We herein genotyped three SNPs (rs1121980, rs72803657, and rs4783818) in FTO to investigate the influence of FTO polymorphisms on individual susceptibility to CAD.

Cerebrospinal fluid β2-microglobulin promotes the tau pathology through microglia-astrocyte communication in Alzheimer's disease.

Background: Cerebrospinal fluid (CSF) β2-microglobulin (β2M) has been demonstrated as an important factor in β-amyloid (Aβ) neurotoxicity and a potential target for Alzheimer's disease (AD). However, more investigation is required to ascertain the relationship between β2M and glial activities in AD pathogenesis.

Multienzyme cascade for synthesis of hydroxytyrosol via engineered Escherichia coli.

Hydroxytyrosol, a fine chemical, is widely utilized in food and pharmaceutical industries. In this study, we constructed a pathway to produce hydroxytyrosol by co-expressing tyrosin-phenol lyase (TPL), L-amino acid dehydrogenase (aadL), α-keto acid decarboxylase (KAD), aldehyde reductase (yahK) and glucose dehydrogenase (gdh). We changed combinations between plasmids with different copy numbers and target genes, resulting in 84% increase in hydroxytyrosol production.

The protein circPETH-147aa regulates metabolic reprogramming in hepatocellular carcinoma cells to remodel immunosuppressive microenvironment.

Metabolic reprogramming fuels cancer cell metastasis and remodels the immunosuppressive tumor microenvironment (TME). We report here that circPETH, a circular RNA (circRNA) transported via extracellular vesicles (EVs) from tumor-associated macrophages (TAMs) to hepatocellular carcinoma (HCC) cells, facilitates glycolysis and metastasis in recipient HCC cells. Mechanistically, circPETH-147aa, encoded by circPETH in an m6A-driven manner, promotes PKM2-catalyzed ALDOA-S36 phosphorylation via the MEG pocket.

The study was to explore the efficacy and safety of sivelestat (SV) in the treatment of severe acute pancreatitis (SAP) with systemic inflammatory response syndrome (SIRS). A total of 102 SAP patients diagnosed and treated in the Emergency Intensive Care Unit of the First Affiliated Hospital of Zhengzhou University from January 2021 to August 2024 were selected. The changes of disease outcome, hospital stays and mortality were compared between the two groups.

Chitooligosaccharides promote diabetic wound healing by mediating fibroblast proliferation and migration.

Diabetic wounds are notoriously difficult to heal due to impaired cell repair mechanisms, reduced angiogenesis, and a heightened risk of infection. Fibroblasts play a vital role in wound healing by producing extracellular matrix (ECM) components and various growth factors, but their function is inhibited in diabetic wounds. Chitooligosaccharides (COS), intermediate products of chitosan degradation, have shown efficacy in promoting tissue repair, yet their role in diabetic wound healing remains underexplored.

Determinants of outcomes in patients with hepatitis B virus-decompensated cirrhosis.

The role of pre-treatment HBV DNA levels on the prognosis of hepatitis B virus-related decompensated cirrhosis is unclear. This study investigated the effects of pre-treatment HBV DNA and other determinants on short-term and long-term survival of chronic hepatitis B (CHB) patients with decompensated cirrhosis. A total of 278 cirrhotic decompensated CHB patients treated with entecavir or tenofovir disoproxil fumarate were retrospectively enrolled.

Dietary amino acids promote glucagon-like hormone release to generate global calcium waves in adipose tissues in Drosophila.

Propagation of intercellular calcium waves through tissues has been found to coordinate different multicellular responses. Nevertheless, our understanding of how calcium waves operate remains limited. In this study, we explore the real-time dynamics of intercellular calcium waves in Drosophila adipose tissues.

Drug inhibition and substrate transport mechanisms of human VMAT2.

Vesicular monoamine transporter 2 (VMAT2) is crucial for packaging monoamine neurotransmitters into synaptic vesicles, with their dysregulation linked to schizophrenia, mood disorders, and Parkinson's disease. Tetrabenazine (TBZ) and valbenazine (VBZ), both FDA-approved VMAT2 inhibitors, are employed to treat chorea and tardive dyskinesia (TD). Our study presents the structures of VMAT2 bound to substrates serotonin (5-HT) and dopamine (DA), as well as the inhibitors TBZ and VBZ.

Identification and structure-guided development of triazole urea-based selective antagonists of Arabidopsis karrikin signaling.

The smoke-derived butenolides, karrikins (KARs), regulate many aspects of plant growth and development. However, KARs and a plant hormone, strigolactones (SLs), have high resemblance in signal perception and transduction, making it hard to delineate KARs response due to the shortage of chemical-genetic tools. Here, we identify a triazole urea KK181N1 as an inhibitor of the KARs receptor KAI2.

Inhibition of Bruton's tyrosine kinase restricts neuroinflammation following intracerebral hemorrhage.

Intracerebral hemorrhage (ICH) is a devastating form of stroke with a lack of effective treatments. Following disease onset, ICH activates microglia and recruits peripheral leukocytes into the perihematomal region to amplify neural injury. Bruton's tyrosine kinase (BTK) controls the proliferation and survival of various myeloid cells and lymphocytes.

Polymorphisms in the gene and neuroblastoma risk in Chinese children from Jiangsu province.

Neuroblastoma is the most prevalent extracranial solid tumor among children and exhibits remarkable heterogeneity. The methylation of cytosine to form 5-methylcytosine (m5C) is the primary type of modification found in DNA and RNA. The NOL1/NOP2/sun (NSUN) family, specifically NSUN1, is responsible for the methylation process and has been shown to play a key role in cell differentiation and cancer development.

CircMVP promotes METTL3 activation mediated CTNNB1 m6A modification in the inhibition of colorectal cancer in B7-H3 dependence antitumor immunity.

The effect of immunotherapy for colorectal cancer (CRC) is limited due to anti-tumor immunosuppression. Circular RNAs (circRNAs) are also associated with tumor immunity. The aim of this study was to clarify the regulatory relationship between circRNA and anti-tumor immunosuppression in CRC.

METTL16 suppresses ferroptosis in cholangiocarcinoma by promoting ATF4 via mA modification.
